In this activity, learners will build rainwater collectors to practice meteorology in their own backyard. Collect and analyze data to determine how much rainfall you get in a set period of time.

In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.

In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.

This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.

In this activity, learners determine the elastic and plastic properties of different types of metal wires.

In this optics activity, learners explore interference by adding wax blocks to a ripple tank.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.

In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.

In this activity learners will be creating art using a traditional Japanese art style.

Visitors mix urea with water in one flask and mix calcium chloride with water in another flask. They observe that the urea flask gets cold and the calcium chloride flask gets hot.

Visitors mix water and sodium bicarbonate (baking soda) in a large flask. They then add citric acid to the mixture and stopper the flask. The resulting reaction creates carbon dioxide gas.

Visitors separate a mixture of pebbles, salt crystals, and wood shavings by adding water and pouring the mixture through a strainer.

Visitors incrementally increase the amount of iodate in three different test tubes containing the same amount of a starch solution.

Using recycled materials, learners will design a transportation vehicle to carry an egg in an egg toss (a rudimentary model of a shock absorbent transport vessel).

In this activity, learners build a model of a self-sustaining habitat (growing grass and beans from seeds).

In this activity, learners survey living organisms near where they live or go to school, and create a local field guide.

In this demonstration, learners observe the effects of density and pressure by attempting to make "balloon kebabs." Learners will try to insert a wooden skewer all the way through an inflated balloon

In this demonstration, adult learners create a lava lamp using beer and nuts! Use this pub-themed activity to demonstrate the effects of buoyancy and bubbles.
